I think first one is least pure...

Explanation:

as we know that boiling point depends on different types of alcohol and one more fact is atmospheric pressure...

at one atmospheric pressure , the boiling point of ethanol is 78.37 °C ...

and here one boiling at 79 C is least pure .. as it is very low from original boiling point

second one is around 81 °C it is more better than first

I think it will help you..
